Invasive fungal sinusitis, orbital exenteration, posterior ischaemic optic neuropathy
Invasive fungal sinusitis is a potentially lethal disease that causes painful orbital apex syndrome with ophthalmoplegia and visual loss. The mechanism of ophthalmoplegia and visual loss is not clear, and neither is the role of radical surgery-orbital exenteration. The authors...

Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...

Anterior ischemic optic neuropathy, mean platelet volume, neutrophil to lymphocyte ratio, platelet distribution width, plateletcrit
The aim of this clinical retrospective comparative study was to assess the possible relationship between arteritic anterior ischaemic optic neuropathy (AAION) and non-arteritic anterior ischaemic optic neuropathy (NAION) with blood platelet parameters and neutrophil-to-lymphocyte ratio (NLR). The medical records of...

Posterior ischaemic optic neuropathy is a rare cause of visual loss believed to be due to infarction in the territory of the pial branches of the ophthalmic artery. There is an absence of clinical signs which means the diagnosis is...

Retinal vein occlusions (RVO) are the most common cause of visual loss from retinal vascular disease second to diabetic retinopathy. Vision is lost due to ischaemia, macular oedema and / or haemorrhage which ultimately effects a patient’s quality of life...
Better outcomes from early repair of Type B blow-out fractures
This paper examines whether early, rather than late, surgical repair results in better motility outcomes for a particular subgroup of orbital floor blowout fractures. The authors divide floor fractures into Types A and B, depending on whether or not the...Isolated trochlear (fourth cranial) nerve palsy in an Asian population

Anterior ischemic optic neuropathy, Granulocyte colony-stimulating factor, Intravitreal injection, Neuroprotection, Optic atrophy
In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...

Korean, non-arteritic anterior ischaemic optic neuropathy, systemic risk factor
The authors reviewed the medical records of 45 Korean patients with non-arteritic anterior ischaemic optic neuropathy (NAION) and 45 healthy controls, in order to determine risk factors for the condition in an Asian population. Previous studies looking at risk factors...

Central retinal artery occlusion (CRAO) is a sight-threatening condition resulting from occlusion of the central retinal artery and hypoperfusion of the inner retina. Early on, fundal examination may be normal. The authors present a retrospective case series of 11 patients...
